. SPECIFICATION -fmmflnigpar@ of Letters Paf-.ent No. 771,619,6ated october 4, 1904. Application filed December 14,1903. `SerialvNo. 185,080. (No model.)

.To all whom t may concern: l l

Be it known that I, LEWIS A. Foorrn, a citi- Zen of the United States, residing at Ohicago,`

in the county of lCook and State of Illinois,

have invented a new and useful Improvement in Seal-Locks, of which the following is a specification.

My invention relates particularly to combination locks and seals for use in connection with car-doors and in analogous situations.,

My primary object is to provide a combination lock and seal operating in such aman-- ner that it is impossible to open the door to which the device is applied without first destroying the seal.

My invention is illustrated in its preferred embodiment in the accompanying drawings` in whiche Figure ll represents a broken perspective view of my improved combination lock and seal applied to a cardoor;. Fig. 2, a vertical sectional view taken as indicated in line 2 of Fig. l; Fig. 3, a vertical section taken as indicated at line 3 of Fig. 4L; Fig. 4, a horizontal sectional View taken as indicated at line 4 of Fig. 3 and showing the seal breaker and ejector in its normally retracted position, and Fig. 5 a similar section sh'owing the lseal breaker and ejector in its advanced or ejecting position.

In the preferred construction, A represents 'a casing which isisecurely attached toy the door-jamb A of a car, said casing having a contracted upper chamber a, an intermediately-located larger chamber af, and in a lower plane a keeper or perforated hasp-re-. ceiver lug a2; B, a vertically-reciprocable bolt movable in a guide at the front portion of the casing and provided at its upper end with a forwardly-projecting arm or handle b and intermediatcly with a forwardly-projecting lug 6', working in a vertical slot b2 in the front Wall of the casing; O, a seal, preferably of thin sheet material, such as tin or cardboard, insertible at a vertical slot c, with which the forwardlyprojecting part of the enlarged chamber a is provided and exposed to view at an opening c' in the front Wall of therchamber af, said 'seal resting upon the bottom wall :of the chamber D, a combination seal ibreaker and ejector slidable upon the bottom .of the chamber a and equipped with forlwardly-projecting lugs d, provided with puncturing-points UZ', projecting from the ends d2 lof said lugs; E, actuating means for the mem- `vloer D, comprising a rock-shaft @,having its `ends journaled in the rear portions of the side walls of the chamber a', cam-arms e', engaging the rear surface of the main portion of the member D and having inwardly-projecting lugs e2, working in vertical slots e, with which a rearward extension e* of the 'member D is provided, and a normally depending actuating-handle e5, with whicha projecting end of the rock-shaftA e is equipped; F, a pawl located in the chamber a, and pivoted on a pin f, .supported at its ends by the side walls of the chamber a; F', a spring confined between the rear endof the pawl and the upper wall of the'chamber a, and G a hasp fixed to the door Gr of the car.

The casing A comprises, preferably, a casting and is open at its'rear side to penmit the internal parts to be put in place. When the casing is secured to the door-jamb, it is thereby securely closed. The lug Z2' of the boltB projects across the lslot c whereat the seal is inserted and into a slot g in the front -wall of the chamber ce. When the bolt B is in the depressed position, the lug or seal-retainer b' 'serves eiectually to prevent removal Aof the seal. The rear portion of the bolt is cut away to provide a 'plain surface 7L, against which the front end of the pawl normally bears. The front end of the pawl is serrated and is inclined very slightlyl forwardly and downwardly, so that any effort to raise the bolt before the pawl is released causes the pawl to grip the bolt the tighter. The bolt extends between the lugs d of the member D, or, in other words, the forward extension of the member D is slotted to receive the bolt and to permit the member to be thrust forwardly in ejecting the seal. The member D is provided at its upper portion with a rearward extension le, having an inclined upper surface c, which serves when the member D approaches the forward end of its traverse to lift the rear end of the pawl' F, thereby releasing the pawl from the bolt and permitting the latter to'be raised, so that the hasp canv transversely at its upper portion to receive the rock-shaft e and cut away along vertical lines at its sides to accommodate the arms e of the member E.

From the foregoing detailed description the operation of the improved device will beV readily understood. Assuming the bolt to be in its raised position, the hasp may be placed upon its keeper and a seal inserted at the slot c. The bolt may then be depressed to secure the hasp on its keeper and prevent removal of the seal. After depression of the bolt the locking-pawl serves normally to preventthe bolt from being raised. Vhen it is desired to open the car, the handle e5 is drawn forwardly to the horizontal position, thereby turning' the rock-shaft e and causing the cams e to move the seal breaker and ejector forward. W hen the points CZ engage the seal, they puncture the same, and as the member D continues to move forwardly the shoulders Z2 engage the rear surface of the seal and force the seal out through the opening c', the seal in the last portion of the operation having its margins bent rearwardly, so that it is utterly destroyed. rIhe opening c' flares outwardly, as shown, to prevent the seal from sticking. As the member D nears the forward end of its traverse the bevel surface le engages the pawl in the rear of its pivot. thereby releasing the bolt and permitting the same/to be raised, so that the hasp can be removed from its keeper. Y

In the improved construction it will be ohserved the bolt is equipped with means for preventing removal of the seal and a combination seal breaker and ejector is equipped with means for releasing the locking-pawl engaging the bolt, so that single operation of the mechanism provided' serves to puncture and eject the seal and release the lockingpawl.

Since the improved device renders it practicableto use plain disk seals and renders the use of sealing implements unnecessary, it is obvious that the seals may be produced at greatly-reduced expense and may be much more conveniently handled and applied than when lead sealing blocks and shackles connected therewith are employed. i

Since', seals are used in vast quantities in connection with cars and in many other situations, it is obvious that the improved device is of great practical advantage. The seals themselves may be of any suitable material, it being desirable that they Vshall either be Yfrangible or/readily puncturable, however.

VVhere -p'asteboard seals are employed, they are `suitably coated to protect them from moisture.

Vhere tin seals are employed. they are preferably painted or coated to protect their exposed surfaces. The characters used on ythe seals are of course printed. embossed, or

`with perforations to permit them to be strung in consecutive order.

Changes 1n details of Yconstruction within the spirit ofl my invention are contemplated.

V'Hence no undue limitation should be understood from the foregoing detailed description. VVhatI regard as new, and desire to secure by Letters Patent, is-
